Apparatus, electronic apparatus and method for adjusting jitter buffer

摘要

An apparatus, electronic apparatus and method for adjusting jitter buffer is provided. A previous jitter buffer size based on a jitter buffer size determined according to an adaptive jitter buffer size calculation algorithm is applied in predicting a jitter buffer size of future time such that the predicted jitter buffer size is applied to obtain a jitter buffer size of a valid time. The audio quality of the speech transmitted over a packet switched network is enhanced.

主权项

1. An apparatus for adjusting a jitter buffer, the apparatus comprising:
a jitter control unit configured to receive a jitter buffer size of a second time, succeeding a first time; a jitter buffer predicting unit configured to estimate an estimated jitter buffer size of the second time by use of at least one auto-regressive moving average (ARMA) model based on a buffer size of the first time, and a jitter buffer selection unit, at a moment of the second time, configured to select a minimum between the estimated jitter buffer size of the second time and the received jitter buffer size of the second time before size adjustment as a jitter buffer size for buffering.
